ARM and their partners are developing a range of low-power, low-cost solutions for smart meters. These highly integrated SoCs use the power-efficient ARM Cortex-M processor family with optimized physical IP, and are produced in the industry proven TSMC 0.18-µm, ultra-low-leakage process. They can be used in standalone smart meters or in appliances that combine power monitoring with other tasks. The meter concept can further extend to a variety of applications, including industrial, consumer and medical systems.
